Estimator¶

class Estimator(*, options=None)[source]¶

Bases: BaseEstimator[PrimitiveJob[EstimatorResult]]

Reference implementation of BaseEstimator.

Run Options

shots (None or int) -- The number of shots. If None, it calculates the exact expectation values. Otherwise, it samples from normal distributions with standard errors as standard deviations using normal distribution approximation.
seed (np.random.Generator or int) -- Set a fixed seed or generator for the normal distribution. If shots is None, this option is ignored.

প্যারামিটার

options -- Default options.

রেইজেস

QiskitError -- if some classical bits are not used for measurements.

Methods

`run`	Run the job of the estimation of expectation value(s).
`set_options`	Set options values for the estimator.

Attributes

circuits¶

Quantum circuits that represents quantum states.

observables¶

Observables to be estimated.

options¶

Return options values for the estimator.

parameters¶

Parameters of the quantum circuits.

রিটার্নস: Parameters, where parameters[i][j] is the j-th parameter of the i-th circuit.
